AIR RECEIVER FOR COMPRESSORS.

Application filed August 4, 1926.

This invention relates to compressors, but more particularly to an air receiver for compressors ofthe portable type.

The objects of the invention are to insure thorough. drainage ot accumulated moisture from the receiver, and to prevent the passage of such moisture into the mechanism in tended to be actuated by the pressure Huid.

Other objects will appear liereinafter.

The invention consists of the combination of elements and features of construction substantially as hereinafter described and more particularly pointed out in the appended claims and illustrated inthe accompanying drawings, in which The figure in the drawing is a sectional elevation of a receiver constructed in accordance with the practice of the invention.

Referring` to the drawings, a receiver designated generally by A comprises a cylindrical casing B having end heads C secured thereto by the usual rivets D. The casing B is provided with an inlet opening E intermediate its ends for the admission of pressure fluid into the casing, such pressure iuid being conveyed thereto by a pipe F leading from a compressor (not shown).

The present invention is more particularly intended for receivers used in connection with portable compressors in which it is not atall times possible to place the receiver in a horizontal position. As is well known in compressing air, a considerable portion of the moisture entrained by A,the air is condensed and deposited in the receiver. Unless provisions are made for preventing the passage of such moisture into the supply line leading from the receiver, the excessive moisture will tend to freeze up the exhaust ports of the mechanism intended to be actuated. Another undesirable feature frequently caused by the presence of excessive moisture in the pressure Huid is that the moisture or water when admitted into rock drills, or the like, will wash away the lubricant and thus cause undue wear on the reciprocatory parts of such mechanisms.

The present invention is intended to Overcome these objectionable features and to this end outlet openings G and H are formed in the casing B at or near its ends. By thus locating the Outlet openings, any moisture which may accumulate in the receiver may readily be drained therefrom irrespective of seriai No. 127,057.

the degree of inclination of the receiver the horizontal.

Suit-able means are provided for collecting the condensed moisture flowing' from the casing B. To this end drain tanks J and K are secured to the casing B adjacent the outlet openings G and H respectively over which they are seated. The drain tanks J and K may be secured to the casing A in any suitable manner, rivets L being shown in the present instance.

Leading from the drain tanks J and K are a pair of pipes O and P. These pipes are secured at their other ends to al suitable connection Q, from which leads a conduit R. for conveying the pressure fluid from the drain tanks to mechanism intended to be actuated thereby. The pipes O and P are preferably connected to the drain tanks J and K near the upper ends of the tanks and thus also well above the level of the water in the tanks to prevent the admission of such water into the conduits leading therefrom.

In the present instance the drain tanks J and K are provided with internal downwardly extending nozzles S adapted to register with the outlet openings G and H. The outlet openings T of the nozzles S preferably lie below the pipes 0 and P' so that when moisture is fiowing through one or the other of the nozzles S it will be prevented from being drawn into the conduits leadingfrom the drain tanks. The drain tanks J and K are in this instance provided with drain cocks U which may be opened Occasionally to drain the moisture from the drain tanks.

I claim l. A pressure fluid receiver for compressors and the like, comprising a casing having an inlet opening, said casing also having outlet openings at its ends to permit the eduction of pressure fluid and drainage of moisture from either end of the casing, a conduit for conveying pressure iuid from the casing, and means interposed between the Out-let openings and the conduit for collecting such moist-ure and preventing its passage into the conduit.

2. A pressure fluid receiver for compressors and the like, comprising a casing having an inlet opening', outlet openings at the ends of the casing, a conduit for conveying pressure Huid from the casing, and

from

means associated with the outlet openings and the conduit for preventing tlie passage of accumulated moisture from the casing into tlie conduit. 5 3.*Apressure fluid receiver for compressorsfand the like, comprising a casing having an inlet opening, outlet openings at the ends of the casing,

the outlet openings to receivepressure fluid and accumulated moisture from the casino'.y and a conduit for conveying pressure fluid from the drain tanks, said conduit beingl con-` nected to the upper end of the drain tank toprevent the admission of 'moisture into the said conduit.

l. A pressure luid receiver for compres- I sors and tlie like, comprising a casing liaving an inlet opening, outlet openings at the ends of tlie oasingllain tanks adjacent the outlet openings to receive pressure 'luid and accumulated moisture from the casing', nozzles in the drain tanks to register with tlie'outlet openings, and a conduit for conveying pressure fluid from the drain tanks,

drain tanks adjacent said conduit being connected With the drain tanks above the outlet openingsioit the nozzles to prevent the admission of moisture into the said conduit.

5. A pressure fluid reeevier for compres sors and the like, comprising ahorizontal casing having` an inlet opening in one side, said casing' havingoutletl openings in the opposite side, said outlet openings being located vnear the ends or the casing to permit the passage of pressure fluid and moisture 'from either end oii'tlie casing', drain tanks seated over the outlet openings to receive suoli moisture and pressure yfluid, a ronduit conveying pressure fluid from tlic drain tanks, nozzles in die upper ends oi the drain tanks registering with tite outlet openings, said nozzles *extending downwardly belouT the inlet opening of tlie conduit to prevent the admission oi' moisture into the said conduit. l

in testimony whereof have signed this speeiiication.l
